Editing embedded or linked content relies on OLE. OLE display is resolution-dependent. This is why you'll find a bazillion questions along the lines of "I changed my monitor and now I see a different number of columns in an embedded Excel sheet".
When you're running a system with multiple resolutions, OLE doesn't know which resolution to use. But it automatically falls back to a workaround: instead of editing the file in place (the normal consequence of double-clicking on an embedded selection), Office opens Excel and allows you to change your selection there so you can repaste it into PowerPoint.
In PowerPoint, you can click on File>Feedback, click the Send a Frown button. And describe the problem in detail, including all steps to replicate the issue. Submitting will send the report to Microsoft programmers. However, since they've already programmed a workaround, it seems likely they're already aware of this.
